I don't have a deep emotional appreciation of it either but small talk is pretty simple to understand. It equates roughly with grooming in animals, while during grooming the physical act of removing parasites and maintaining hygiene is what's happening it's not the sole function in fact it's probably not even the main function. Grooming, like small talk, is a a way of reinforcing social bonds and maintianing/delineating social hierarchy.
Same with humans, you make people feel good when you engage in small talk and they do the same for you, it's a cooperative thing and if one side isn't cooperating the other has every right to be annoyed (according to social rules). The other thing small talk does is fill time which is the main reason humans engage in any activity. How to do small talk is a different matter but the above is what it's for. Transactional analasys explains it very well.
Needing friends is obvious really. You wouldn't be here if you didn't need human contact of one kind or another. If you didn't get any you'd shrivel up and die figuratively speaking.
The art of conversation is hard and I've not got very far yet but I do know it's in the listening and not the speaking. Listen and react to what people say rather than preparing a statement to give them once they've finished speaking. Ask questions and avoid beginning sentences with the word 'I'.
For an aspie to converse properly you need to study body language. There's no other way you can tell how a person is reacting to what you're saying, evolution has given humans (most humans lol) control over their facial expressions and even more control over our words (via our massive brain) so they are next to useless for determining how the other feels. Body language is the only way and without studying it you'll never know it. I see a lot of aspies who say they can read others and it's just not true unless you do the homework, aspies can read when others are really annoyed very upset or extremely angry yes but if you know body language you can tell long before they reach those extreme edges of emotion that what you're doing is upsetting the other. Sorry I've a bee in my bonnett about that subject.
Honestly I don't think any of the above will ever come naturally for us but if we work at it, really work at it, we can at least stop ourselves from cmaking the same mistakes time and again and at best we can become proficient. All depends on how you apply yourself in my opinion. It's just a shame it's not always so easy to apply onesself.
